I think serge has linked the wrong patch. The culprit is https://reviews.llvm.org/D59634, which does add the dependency because it uses the Object library to construct the ObjectYAML model. This is a new dependency because for all the other binary formats the code to construct the yaml model lives in tool code (obj2yaml). Here, I chose to do that in the ObjectYAML library because I wanted to make that code accessible to unit tests.

@jhenderson do you see any problems with this new dependency (i.e., should I push a patch adding it), or does it need more discussion (i.e., revert the original patch) ? (FWIW, to me it seems natural for ObjectYAML to depend on Object, and I don't think this creates any danger of dependency cycles, as Object should never depend on ObjectYAML.)
